This listing is for a complete replacment CD mechanism and associated electronics as removed from a Bang & Olufsen Ouverture and is in excellent working order. This can be used as a direct replacment for the later CDM12 type lasers, all the connectors are the same and are long enough to reach, I can supply full instructions if required to fit the laser as required, if you contact me I can confirm if this will fit your B&O. The CDM4 is used in many other CD players and should be suitable as a replacment. I am happy to ship worldwide but please check shipping costs as these will be less than listed by ebay
